Identifying Your Marine Generator
We are in the process of changing the brand names of some of our Cummins Onan Marine generators. Please use the reference list at the bottom of this page to identify the old and new brand names.
If you are looking for an older marine generator model you can try the Historical Models page.
When contacting a Cummins Onan dealer for service or product information have the model and serial numbers handy.
To order the correct Cummins Onan parts and manuals from a Cummins Onan-certified dealer/distributor or to download an Operator's Manual from this site, you'll need to know the model and spec of your generator set. If you don't already know this information, the steps below will help you identify it.
1. Can you read the information on the nameplate?
The model and spec of the set are indicated on the nameplate. The spec is the letter at the very end of the model information. Depending on the age of your set, the spec may or may not be clearly identified for you. Here is an example of a nameplate for a model KY spec K:
2. If you can't find or read the nameplate, can you find a serial number stamped on the generator set?
Call the Cummins Onan Customer Response Center with the serial number at 1-800-888-ONAN (1-800-888-6626). Press 3 when prompted by the recording. They'll help you identify the model and spec letter you need to order parts and manuals. If you can't find the serial number on your set, they can help you determine where to look for it.
3. If none of the above helps you identify your Cummins Onan generator set, please contact a Cummins Onan distributor or dealer.
Without nameplate information or a serial number, you may need to have a Cummins Onan dealer in your area look at the set to identify it. To find the nearest location, use the Cummins Onan Dealer Locator or call 1-800-888-ONAN (1-800-888-6626) and press 1 when prompted by the recording.
